Macbook Pro (M1), macOS Monterey 12.5.1
2560 x 1440 external monitor

Most lightning resolutions do not work. I click on it and nothing happens. The resolution stays as per last valid command.
The resolutions without lightning work "fine" but are very blurry/pixelated.

So far, only those two work:

• 1280 x 720 ⚡️
• 1024 x 576 ⚡️
  (Not even 2560 x 1440 ⚡️ does work)

Is there anything to change ?

External monitor off does not recognize the resolution

Good evening everyone,
I installed your RDM app on MacBook 16, while setting the various resolutions, with the laptop screen closed (clamshell) the screen went black and no longer found the correct resolution.
I was no longer able to set it from the Mac's screen settings because it seems that RDM does not update the settings.

In dual display mode it works and sets the various resolutions of the two screens, but I can no longer use only the external screen with the lid of the Macbook closed.

How do I fix this problem? Is there any way to delete some external monitor configuration file created by RDM.

sorry for the English language

Thanks

Right now, if I plug in or unplug a display, or change a resolution or orientation of a display using another tool, I need to restart RDM for it to show that new data. It would be great if it detected these changes and showed them automatically.

usr-sse2@d20ee34 seems to implement this functionality, so might be a good place to start (maybe try to get @usr-sse2 to do a pull request?).

Hey Guys and Gals,
I have no Idea about programming, but I wonder if it's possible to set Apple's ProMotion display to a certain frequency, which is not in the list. I do live renderings - currently on 50 Hertz - but I have the feeling that I could save performance - and energy - if the refresh rate of the display (and with it all the displayed things) - are live-rendered/refreshed at/with just 25 times a second, instead of 50 times. The final live rendering has a target fps of exactly 25 fps. Sometimes I'd need the same but for exactly 30fps.

Thank you so much for considering and/or thinking about (this maybe weird) thought.

Thx so much,
Jo

Hello,
Thanks for the great tool. But I have some problem.

1720x720 HiDPI does not work for me but non-HiDPI resolution works.
Currently I'm using 1720x967.... but I have a black border on both sides.
I want to use 1720x720 HiDPI.

I'm currently using RDM 2.3.1 and I wonder if there is a more recent version.
Or, is there an appropriate solution?

I want to be able to change the screen resolution from the command line

Should it appear in the bar above automatically?

Hi,
More than an issue, this is a request (could't figure out where to put it).
Love RDM. I use it on a headless mac mini, but the thing is that because it's headless OS X always defaults to a resolution of 1280x1024.
Every time I log on after the mac reboots, I have to manually change the resolution. Is there a way for RDM to save a resolution, so that next time it loads, it goes back to that one? (or to do a command load with a specific resolution?)
Thanks.

Would it be possible to add rotation (0°, 90°, 180°, 270°) to the menu bar? I’ve found that vertical monitors aren’t so useful when screensharing, and so I’d like a quick way to switch between rotations when I spin a monitor around.

I tried to create a custom resolution (2560x1080 HiDPI) on my M1 Macbook Air running Monterey but it won't show up. The custom resolution would show on my 2018 Mac mini running Monterey. Any help would be appreciated.

First, thanks for the great tool. I have noticed that when I operate in the clamshell mode, I am unable to set the two external monitors to the ⚡ resolution. Moreover, although the resolution in and out of the clamshell mode remains the same (in my case 1980 x 1200), there is a noticeable difference in the picture quality due to the absence of ⚡ resolutions in clamshell mode.

Below is a comparison of the image quality and difference in the normal and clamshell modes.

Hello,

I used RDM a long time now and it worked like expected. But now I have the following problem with a HIDPI resolution:

I'm using a MacBook Pro 2016 with the external montitor DELL U2515H.

A non-HIDPI resoltion works fine but with blurry text etc.

Does anybody knows how to fix the black border at the top and bottom?

Greets,
Patrick

Maybe it is a better to ask the original author.

I have 1280x800 HiDPI listed but I can not set it. I modified the code and get CGError 1007. I can not set 1280x720 HiDPI with two black bars on top and at bottom. I also have the same issue on another monitor. 840x525 HiDPI is listed but can be set.

Is it a upstream error of apple's api?

I have a 2560 x 1440 Dell external monitor.
when I select a retina mode (ex: 1920x1080 ⚡️) from the RDM menu, everything looks sharp and dow scaled to 1080p but when I take a screenshot or a screen recording I realised that the resolution is actually 3840 × 2160 instead of 2560 x 1440!

How can I solve this?

As the title, a monitor with 2560x1440 cannot use the right resolution（16:9），just like 1920x1080,1280x720

Not sure what I'm doing incorrectly, I've disabled csrutil and followed these instructions but nothing happens when I attempt to change to 1920x1080 HiDPI.

I also tried 960x540 hidpi and it doesn't work either.

Every other mode works.

I'm using this LG monitor.

The app works fine with the arm chips, but it'd be nice to not have it running in Rosetta 2.0 and draining battery more than it needs to because of the arm -> x86 translation. Thanks!

Easy question

Hello :)

How do I uninstall RDM?
Should I simply delete the RDM.app file in the Application folder? Or is there additional steps to take? I don't know what was modified during installation.

Best,
-a-

usual use The normal resolution is 500mb

I have an HP Z24i Display with native resolution of 1920 x 1200. I want to run it as 960 x 600 in HiDPI. Selecting that option from the menu does nothing. The menu doesn't even update to reflect that I've selected that options. Most other HiDPI options work, such as 1280 x 800, 1280 x 720, 840 x 525, etc. It seems that only 960 x 600 and 960 x 540 refuse to work.

Any idea what's going on here? I'd really like to use 960 x 600 since that's best for this display.

Thanks.

Why is there no binary for the inexperienced users?
(When others see the benefits of using RDM I am often asked about the program and where to get this.)

It is not too difficult to provide a binary from the sources. And if there are many (for every change) or only a few (for every pull request) versions, it doesn't matter, as long as you declare them as "beta" or "at your own risk" everything is clear.

Of course I have a link to make my compilation available to friends and relatives. But as a competitor to the project here, it makes no sense to offer my links publicly. The binaries should be offered here!

((btw: a binary today should support (2022/02) MacOS 10.13 - x.x...))

Sorry, I'm new to GitHub. How am I meant to install the app? I downloaded it to my Downloads folder and extracted the .zip so there is a folder called "RDM-master" in my Downloads folder. I ran "Makefile" but after that I am not sure what to do. I am on MacOS Mojave 10.14.1.

Hi, I hooked my macbook pro retina to a 4K TV, and there's a 1900x1080 lighting option in RDM for the TV but whenever I chose that option, my mac kept logging out, please tell me why this happened and whether it can be fixed or not.

Currently my screen has a different aspect ratio then the normal one and because of that all HiDPI resolutions that I can choose from are creating a big BLACK rectangles on both sides of the screen.

It will be nice if we can write a custom HiDpi resolution since we know the actual resolution of the screen.

Would it be possible to display the aspect ratio of each resolution in the menu app? I frequently switch resolutions but prefer to only stay in my Macbook's aspect ratio of 16:10. Perhaps this could be extended to a toggle that only displays specific aspect ratios in the menu selector.

Similar to this (from another app).

From other issues postes I see that there is an option to edit the available modes at the bottom of the list of available modes, this does not appear in the menu for me.

Hi!

If i shutdown the system and then restart it, I need to re-select the resolution. Is it possible to make permanent?

RDM 2.2.
macos 11.1
m1 arm mac

I have only got those options.

I have tried to press the edit... button to add a new resolution 2560 x 1080, then reboot. Okay, i applied it but the result is not like what i thought.

The screen didn't expand with the full height and width...

I have tried to install rdm 2.2 in my computer (10.11.6). But the icon of RDM has a prohibiting sign and doesn't work.
However, the 2.1 works.

Thanks.

Can I have the super high pixel density but "looks like" 1920x1080?

I.e. I've set it currently to 1920x1080, but I don't think it's using all the pixels

Hi,
I found what I believe to be a bug. Right now I'm able to use both monitors with the desired custom resolution.

My setup:

• MacBook Pro 13 TB 2019
• TB3 to 2xHDMI adapter
• Dell U2515H
• Dell U2518D

I was trying to use a custom resolution of 1920x1080 and HiDPI(my monitors specs are for 2560x1440).
Through RDM list, setting 1920x1080 was working, but no HiDPI. So I tried to set a custom resolution. It didn't work.
Tried creating other resolutions, but it wouldn't appear on the resolution list.

I disconnected one monitor at a time and, when plugged back in, RDM showed the new custom resolutions and the monitors were able to change. The steps I followed were:

1. Create custom resolution, adding all the Unknown flags
2. Save the new profile
3. Unplug screen no.1
4. Plug it back in
5. Go through the resolution list, find the custom one, set it to screen no.1
6. Unplug screen no.2
7. Plug it back in
8. Go through the resolution list, find the custom one, set it to screen no.2

Comment 1:Apparently, it seems that this rough "reset" of the screens are needed for RDM to show the new custom resolution and the monitors to accept it.

Comment 2: RDM listed the new custom resolution on the second screen before following steps from 5 till the end. However, it wouldn't accept the custom resolution. Only after disconnecting and reconnecting, it accepted.

Since I'm also running ddcctl from this, I'll try changing inputs and going back to macOS and post it here. It might help someone.

Hey folks, can someone share instructions for removing RDM properly?
I've read about folks having challenges removing all sorts of config residues.

Thanks

It doesn't show my 1680x1050 on 2-nd monitor. I have it on 1-st, but on 2-nd I have 1400x1050, 1600x1200 and 1920x1080

Exactly what the title says, whatever resolution or scaling I provide, nothing happens.
Listing modes and displays does work however.

Hi!

Great utility, and found it in a very timely manner... Before getting to it, I had found cscreen (https://www.pyehouse.com/cscreen/) which unfortunately doesn't work on my setup (High Sierra, Retina displays)... But this tool has a very handy feature which is changing the menu bar location.

So the -p option allows moving the "reference" menu bar location to a different display (making it the "default" one), and the -i option allows referencing displays using an permanent ID, regardless of what the "connection" order is:

So, being able to "move around" the menu bar would be incredibly handy - just a suggestion

The help screen from the tool:

Usage: cscreen [-d <depth>] [-x <width>] [-y <height>] [-r <refresh>] [-s <display>] [-v] [-m] [-f] [-l] [-h]
           [-d <depth>]    : specifies the bit depth (bits per pixel)
           [-x <width>]    : specifies the width in pixels
           [-y <height>]   : specifies the height in pixels
           [-r <refresh>]  : specifies the refresh rate in Hz
           [-s <display>]  : specifies which display to use (defaults to main display)
		   use a as the option to -s to specify the action on all displays
           [-i <displayID>]: picks a display based on CGDirectDisplayID (permanent per display)
           continue to use '-s a' for "all displays"
           [-v]	           : display valid modes (use -s to specify display or nothing for the default)
           [-m]            : require an exact match
           [-f]	           : forces settings (ignores safety mechanisms; USE AT YOUR OWN RISK)
           [-l]            : lists the current displays and modes
           [-p]            : sets the requested display to have the menu bar
           [-h]            : displays the usage
           
           Note: Using -p will change the display index so you will likely want to use -l again to show the current
           displays if you wish to use -p a second time.

Could you consider adding support for this?

Hi, thanks for sharing that, I'd like to use 2048x1152 resolution. Is that any chance to add it?

Thanks

The app overall works, however from time to time especially when I disconnect/reconnect the screen it starts flicking and going off and on and loosing signal.

The only way to make it work is to choose a non HiDPI resolution and then to go back to HiDPI resolution.., which is less than ideal.

Hello,
I just wanted to know if it's possible to add custom resolutions. As I'm on my MacBook Air 11" i can't really use 1920x1080 cause the UI is too small. I'd like to add a 16:9 resolution between 1366x768 and 1440x900 - would that be possible? If yes, how?

Thanks in advantage!

RDM does not compile for current versions of macOS. I created a pull request to fix that: #51

I wonder how to make RDM work for a 21:9 monitor with 2580x1080. There are no proper HiDPI resolutions given in the menu.

something like this:

cask 'retina-display-manager' do
  version '2.2'
  sha256 '4baba78e89fb36ae022d5a234bb968402503ed277af59ae72e8270e9b6bef895'

  url 'http://avi.alkalay.net/software/RDM/RDM-2.2.pkg'
  name 'RDM-2.2.pkg'
  homepage 'https://github.com/avibrazil/RDM'

  app 'RDM.app'
end

I use the 1920x1080 one atm to make my MacBook's screen 16:9, but it looks much lower resolution than APple's defaults.

I'd like a HiDPI 16:9 option? Possible?

I don't have any prove but I think RDM resolution settings remain after uninstalling, I have reasons to suspect the lightning 16801050 is different from the original apple display settings 16801050, cause its affecting performance on some full screen applications on which I tested on others similar (same specks) macbook pros without RDM, so im guessing is something to do with the Re scaling of 3360*2100 has differences..... I do not know

Currently I can't have the option of doing a full restoration of MacOs to test performance on a clean OS, so I rely on knowing but if there is some way of making sure I uninstall RDM properly and returning to fully default settings, maybe involving some terminal commands I ignore

sorry for my inexperience and/or if this is a silly Issue, thanks for reading anyways.

HiDPI scales everything 2x which is needing too many resources on my Macbook when using the scaled resolution 1440p because it is calculated as 5K.

So is there a possibility like on Windows to stick to 4K which is the native resolution of my external monitor and simply scale the UI differently (e.g. 125%)?

I am using macOS Catalina 10.15.4.

Hello,
I'm not sure whether it is the proper use for this application, but let me explain what I am trying to achieve.

I have 1920x1080 Asus VH242T external display, that I connect to my mid-2014 13" rMBP with HDMI-to-DVI cable or with miniDP-to-HDMI, then HDMI-to-DVI.
In RDM I can't select 960x540 (exactly half of 1920x1080) HiDPI mode. I click on it, but nothing happens, the output resolution does not change.
All other resolutions work fine.

I tested with another 1440x900 display (selecting 720x450 HiDPI) and it behaved the same way - did not work with this particular resolution but worked with any other.

Could this possibly be a bug in RDM? Thank you.
